             Summary: Enable dynamic update of client-side SSL factory in brokers
                 Key: KAFKA-8336
                 URL: https://issues.apache.org/jira/browse/KAFKA-8336
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 2.2.0
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 2.3.0


We currently support dynamic update of server-side keystores. This allows expired certs to be updated on brokers without a rolling restart. When mutual authentication is enabled for inter-broker-communication (ssl.client.auth=required), we dont currently dynamically update client-side keystores for controller or transaction coordinator. So a broker restart (or controller change) is required for cert update for this case. Since short-lived SSL cert is a common usecase, we should enable client-side cert updates for all client connections initiated by the broker to ensure that SSL certificate expiry can be handled with dynamic config updates on brokers for all configurations.
